“…In sum, a growing body of research using economic games has illuminated the role of personality traits—especially politeness and compassion, but also openness/intellect—in basic prosocial tendencies towards fairness, helping, and cooperation. Although we have focused here on the Big Five domains and their narrower aspects, alternative models of personality, such as the HEXACO (Honesty‐Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, and Openness to Experience; see Anglim & O'Conner, , this issue) and the Dark Triad (psychopathy, Machiavellianism, and narcissism; see Koehn, Okan, & Jonason, , this issue), subsume additional traits linked with economic game behaviours, as summarised in Table (see Zhao & Smillie, , for a review).
